Older Teenage Girls Now Vape More Than Boys, Reversing a Long-Standing Pattern
Regular teen vaping has shifted in a direction that few pediatric practices were prepared for: older adolescent girls now use e-cigarettes at higher rates than boys. The pattern is especially clear among youths ages 15 to 17, where regular vaping among girls climbed from 4.9% in 2021 to 7.8% in 2024, while the rate for boys stood at 4.6%. In a behavior historically driven by male-heavy nicotine use, the reversal matters because it changes which patients may be most exposed to nicotine dependence, respiratory irritation, and downstream addiction risk during a narrow window of brain development.
The data come from national survey information collected from 2014 through 2024 and analyzed by researchers at the Medical University of South Carolina Hollings Cancer Center. The work appeared in JAMA Pediatrics and focused on regular vaping among youths ages 12 to 17. It was observational, so it was not designed to explain why girls overtook boys. Even so, the trend itself is clinically important. A simple screening habit built around older assumptions can miss the patients now most likely to be using these products.
One sentence captures the shift clearly: the gender gap flipped.
For pediatricians and family physicians, the implication is straightforward. Nicotine exposure during adolescence can reinforce dependence pathways at a time when executive function, impulse control, and reward circuitry are still maturing. E-cigarettes are often marketed and perceived as less harmful than combustible tobacco, but the clinical problem in teen patients is not only comparative harm; it is sustained nicotine delivery, behavioral reinforcement, and the possibility that repeated exposure becomes normalized before adulthood. When use concentrates in one demographic group, screening has to follow the epidemiology rather than old stereotypes.
Survey Trends Point to a Rapid Change in Adolescent Nicotine Use
The national survey data span a decade marked by major changes in the youth nicotine market. What makes the recent pattern stand out is not just that girls surpassed boys, but that the rise among older girls was strong enough to approach the 2018 to 2019 peak seen in earlier waves of vaping. Among teens ages 15 to 17, the 2024 rate of 7.8% among girls sits close to that earlier high-water mark, suggesting that the reversal is not a statistical blip. It reflects a real and current burden in everyday practice.
Regular use among younger adolescents was not detailed in the same way in the available report, and the study was not built to identify behavioral, social, or product-related causes. That leaves several plausible mechanisms on the table. Marketing, flavored products, peer diffusion, stress coping, and social media exposure have all been discussed in the broader nicotine literature as possible drivers of youth use patterns. None of those explanations can be assigned here from the study itself, but the bedside consequence is unchanged: clinicians should ask directly about vaping, and they should not assume that boys are the primary risk group.
Benjamin Toll, PhD, director of the MUSC Health Tobacco Treatment Program, said pediatricians should pay attention to possible vaping, especially among female patients. The practical value of that advice is hard to overstate. If the highest-risk group is changing, the screening script has to change with it. Adolescents often minimize use, and many will describe vaping as intermittent or social rather than daily. Yet even regular use that does not look dramatic on paper can represent entrenched nicotine exposure, particularly when it begins in middle or early high school.
Why the Reversal Matters at the Bedside
A shift from male-dominant to female-dominant vaping patterns carries implications beyond prevalence counts. Nicotine dependence can be harder to identify when it is embedded in routine social behavior, and teen girls may face different contextual pressures around appearance, stress, social belonging, or weight-related beliefs that do not show up in surveillance data. None of those factors were measured in the survey analysis, but they remain clinically relevant when counseling patients. Physicians who only ask about cigarettes risk missing the product most teens actually use.
The age split also matters. The rise was most visible among older teens, which likely places the highest use burden in patients who are close to driving age, school-to-work transitions, and more independent access to nicotine products. For clinicians, that means adolescent visits should include plain questions about devices, flavors, refill pods, and frequency of use, not just whether the patient smokes. The difference between experimentation and regular use can be clinically important, especially when patterns are changing quickly.
This is also a prevention issue. Earlier identification allows counseling before dependence hardens and before vaping becomes part of a broader nicotine trajectory. E-cigarette use in adolescence is not a neutral habit, and the public health concern grows when a rising share of use shifts into a group that may not have been targeted as aggressively by prior prevention messaging.
A Moving Target for Pediatric Screening and Prevention
The study’s observational design limits causal interpretation, but it does not weaken the signal that pediatric nicotine surveillance needs updating. Survey trends over 10 years can miss the speed with which youth behavior changes, and this one appears to have changed enough to alter who walks into the clinic with the greatest likelihood of use. Girls ages 15 to 17 now sit at the center of the pattern, and that should shape screening, counseling, and school-based prevention efforts.
Public health responses will need to keep pace with product evolution, since the appeal and accessibility of vaping devices can change faster than policy or clinical messaging. For now, the key clinical issue is simple: adolescent vaping is no longer a problem that can be approached with an old male-centric lens. The data now point in another direction, and routine care should follow it.
